Abstract (en)
A control device for an internal combustion engine includes refueling detection means (S105) for detecting refueling, mixing ratio estimating means (S112) for estimating a mixing ratio of alcohol contained in fuel, estimation completion determining means (S113) for determining whether estimation is completed by the mixing ratio estimating means (S112), and ignition control means (S107) for igniting an igniter at an ignition timing that is retarded from an optimum ignition timing based on an actual mixing ratio, during a predetermined period until the estimation completion determining means (S113) determines that the estimation is completed after detection of refueling.
